Field and Laboratory Emission Cell (FLEC) emissions testing is approved as an emissions testing methodology ONLY for furniture and furnishings that are made up of a uniform material and have flat testing surfaces on which the FLEC emissions testing methodology may be applied. For example, flat surfaced cabinetry that is made up of a uniform material may be tested using this methodology. However, chairs that are made from a variety of materials that lack flat surfaces may not be tested using this methodology. The emissions test must be administered by a third party investigator with no affiliation with the project. The associated costs are the responsibility of the project team.

Alternative Adherence Path
Type: Alternative Adherence Path
Post Date: 24 Oct, 2016

Projects may use a permanent entryway system 3 meters long, and an air curtain to create an air seal. There are several specifications for this path:

  1. The air curtain must have a minimum velocity of not less than 2 meters per second (6.56 feet per second) at the floor, have been tested in accordance with ANSI/AMCA 220, and must be installed in accordance with manufacturer's instructions. It must also be commissioned prior to occupancy by a qualified agent.
  2. An indoor pressure sensor must be installed in the building lobby that is capable of providing automatic readings at least once an hour.
  3. The project team must specify target pressurization levels for these locations when the building is occupied. These levels have to keep air from entering the building more than the standard amount, allow occupants to open and close doors easily and not cause moisture problems due to exfiltration. Projects must provide documentation of these targeted levels and ensure they achieve the objectives outlines above.

To document this alternative adherence path, the project team must provide the following in the Documentation Submission:

  • Indoor pressure sensor readings in accordance with ANSI/ AMCA 220 including exhaust and supply sequences from a single day
  • Mechanical drawings of the project space and manufacturer documentation of the air curtain equipment

- The project team must specify the targeted building pressurization levels for these locations for when the building is in both cooling mode and heating mode. The pressure levels must keep outside air from entering the building (more than standard practice), allow occupants to open and close doors easily, and must not cause undue condensation or other moisture problems due to exfiltration through the building envelope.

To document this alternative path, the project team must provide the following in the documentation application submission:
- A narrative describing the targeted building pressurization levels for both cooling mode and heating mode.
- A narrative (and other supporting documentation as necessary) demonstrating that the pressure levels keep outside air from entering the building (more than standard practice), allow occupants to open and close doors easily, and do not cause undue condensation or other moisture problems due to exfiltration through the building envelope.
- Indoor pressure readings demonstrating one day of pressure sensor readings from a cooling period, and one day of pressure sensor readings from a heating period. The exhaust and supply sequences must be provided to demonstrate that the desired pressure readings will be achieved.

The provided lighting analysis document must be updated to demonstrate that 90% for Option 2 or 75% for Option 3 of the regularly occupied floor area meets the requirements (i.e., at least 2 points under LEED v4 BD+C EQ Daylight credit).


Alternative Adherence Path
Type: Alternative Adherence Path
Post Date: 06 May, 2016

Inquiry: Can an automatic shading system that draws shades when sensors indicate that daylight can contribute to glare at workstations be used in lieu of meeting the feature requirements?

Comprehensive corporate wellness programs that offer meaningful incentives for regular physical activity or active commuting may be used to comply with Feature 65. Projects may also create company-sponsored sports teams, provided the sports teams are selected by the employees. Projects should ensure there is capacity to accommodate all employees who elect to participate and work with employees to accommodate similar incentives upon request. Projects must provide supporting documentation that demonstrates that the wellness offerings promote physical activity and incentivize employees to maintain regular levels of activity engagement or active commuting.

Inquiry: In residential units, are the requirements of Feature 76 met if individual unit controls for heating are provided?

Ruling: No, an exemption from ASHRAE 55 requirements may not be granted in residential units if individual unit controls are provided. It is typical for each unit in a multifamily residential development to have individual control over space temperatures with controls allowing occupants to adjust temperatures. In order to rely on the controllability of the systems as an alternative strategy, it must be demonstrated that the local controls allow occupants to set conditions within the unit to meet ASHRAE 55.

Projects can earn one Innovation feature by providing free tours of their WELL Certified space. Projects must include a WELL educational component in conjunction with the tours. This can be permanent signage throughout the space describing different WELL features, a case study surrounding WELL Certification, a newsletter or other printed/online publication following the occupants' engagement with WELL, or an approved alternative. Tours may be offered on a pre-determined schedule or upon request through the IWBI Event Request Form.

In order to receive Innovation approval for an active tour program, projects must provide IWBI with the tour script and tour destination descriptions (including at least one destination per WELL concept) as part of their documentation. On an annual basis, projects must also submit the following documentation to IWBI: dates of tours (minimum of six per year), number of attendees (minimum of 50 per year), and evidence of how the project is broadcasting the availability of these tours (i.e., social media, project website).
